The name of Charlotte Qin was first seen in the Cave Story of Emperor Wu of the Han Dynasty: "A strong woman came from the east to play the piano". The sides of this piano make symmetrical wavy curves (see the picture below). The earliest existing sunset instrument is the Colorful Fengming Instrument made by Tang. Mr. Bai praised it as a "good voice". 1959, the late pianist Mr. Guan Pinghu made two new films, both of which adopted this style and were very loud. According to Mr. Wu Jinglue's experience, the sound of sunset piano is mostly generous. Welcome to "Chua's Musical Instrument Store" to watch and listen to guqin.

The earliest sunset style came from Wei Lei in the Tang Dynasty.
